APPARATUS FOR SOLDERING CANS.

SPECIFICATION forming part of Letters Patent No. 225,543 dated March 16, 1880,

Application filed December 29, 1879.

To all whom it may concern Be it known-that I, FREDERICK WEsrER- BECK, of St. Louis, State of Missouri, have invented an Improved Apparatus for Soldering Cans, of which the following is a specification.

My improvements are designed to greatly facilitate the soldering of cans, to prevent as little of the solder reaching the inside of the can as possible, to prevent the warping action on part of the top or bottom during the appliance of the solder, and otherwise to provide an improved apparatus forsoldering purposes.

I will first fully describe the construction and operation of my improvements, and hereinafter, in the claims, point out the novel features thereof.

Of the drawings, Figure 1 is a longitudinal sectional elevation Fig. 2, a sectional elevation taken on line a- .r, Fig. 3, at right angles to Fig. 1. Fig. 3 is a plan view with the cans and oan'holder or dipper removed, Fig. 4 bein g a plan view of can-dipper.

The stove for heating the solder, &c., I con struct as indicated in the figures, in which A is the stovecasin g 01, its grate; B, the door to the fire-chamber; B, the ash-chamber, and B the stove flue or chimney. O, the top of the stove, is made to be a chamber, reservoir, or pan, as shown, to contain the solder.

My improvements more chiefly relate to the following construction and operation of parts:

The top plate, 0, of the stove (being the bottom of the pan 0) I provide with an offset chamber, D. As shown, this chamber D at D is fitted to accommodate the operation of a rod-shaft, E, and the remaining part of the chamber D fitted toaccommodate the operation of the forward part of a lever, F. The oifset chambers D D therefore protect their said contained parts from the direct effects of the heat. I

- The rod-shaft E has at c a slot to receive the forward end of the lever F. (See Fig. 1.) Fur ther, at c said rod-shaft is made hollow, and at c has one or more lateral openings. (Shown in Figs. 1, 2.) The purpose of the hollow at e and openings 0 is chiefly to form an outlet to return whatever solder enters a can-dipper back to the pan containing the solder, as will hereinafter appear. The rod-shaft E so made passes vertically through a corresponding opening made in the top plate, and in line with the offset chamber D, as shown in Figs. 1, 3.

H is what I term the can-dipper, for it is upon this device that the can is placed and held in proper position while having its edges dipped into the solder, or having the latter applied to the proper point to be soldered.

The can-dipper H consists ofa bottom, It, and its surrounding or vertical sides It, as shown in Figs. 1, 2, 4. The bottom h is made slanting from all sides in the direction to its hollow sleeve 7L2 or outlet. (See Fig. 1.) The top faces of the sides h of the can-dipper can be shaped rectangular, as shown in Fig. 4, and made to support one or more cans, as indicated in Figs. 1, 2, and 4.

The sides h of the can-dipper in all cases are made to suit the different shapes or sizes of cans, so that the latter can be placed top of and supported by the can-dipper for the pur' pose of being soldered.

The can-dipper is therefore a trough-like device, its slanting bottom readily permitting the solder to flow back again through its outletk and the openings 0 in the rod-shaft back into the pan, when said rod shaft is raised.

The can-dipper H, by its sleeve k is screwed or fitted into the hollow of the rod-shaft E,

u and forms part of same. In case, therefore, the rod-shaft is raised and lowered, it carries the can-dipper H with it, and said parts are made to assume the different positions indicated in Fig. 1.

I is a pyrometer, to show the temperature of the solder.

I is a set-screw passing through a standard, 1 placed in line with the lever F, to graduate the throw or action of said lever.

All the parts being thus constructed and ar- IOO ranged, the complete operation is as follows: The cans are placed on top of the can-dipperH so that the edges of the bottom or top of the can project over the bearing-edges of the candipper. (See Figs. 1, 2.) The operator presses with the hand slightly the cans in a downward direction, at same time, with the foot, pressing down the treadle, thus permitting the cans to follow the can-dipper-thatis, to dip the edges of the can to be soldered into the solder. This downward position of the parts is shown in dotted lines. (See Fig. 1.) Here be it noted thatwhatever solder gets into the trough or chamber of the can-dipper cannot touch the can, as a layer of air always exists between said named parts or surfaces. This result is deemed important, as said interposed air protects the bottom or top of the can, as the case may be, in the act of applying the solder. It is therefore only the edges of the can that are reached by the solder, and Where the needed joint is required. An other advantage derived from this action is, that the bottom or top of the can, as the case may be, can be prevented from flying off or becoming loosened by the warping action of the heat, since the operator can keep the cans pressed to their places on the can-dipper. As soon as the solder has been properly applied the treadle is released and the parts assume their original position. The can-dipper being restored to its highest point permits its contained solder to find its level with that contained in the pan.

During the application of the solder to the can its opening is closed by a cover, M, which forms part of the can-dipper H. (See Figs. 1, 4.) This cover It is but an ordinary cover, but

' inverted, as shown, and secured by a stem, 71/4,

k is a pipe controlled by a cock, to be used for emptying the pan of its solder. h represents an ordinary can.

By the use of my apparatus the solder is made to reach the proper edge or edges of the can without in any way damaging any other part of the can, and the solder is applied with the greatest dispatch, neatness, and precision.

What I claim is' 1. In combination with a can-dipper consisting of a bottom, h, having sides h, sleeve 70 the stem 7%, carrying an inverted cover, if, as and for the purposes set forth.

2. In combination with a can-dipper consisting of a bottom, h, having sides h and sleeve 7L2, the rod-shaft E, having hollow at e and openings at 6 by means whereof the contents in said dipper are made to flow through said rod-shaft. as and for the purposes set forth.

3. In combination with a pan, 0, its bottom 0, havingan opening, d, in communication with an offset chamber, D D, said chamber containing the fulcrumed part of a counterbalanced lever, F, connected to a rod-shaft, E, having a hollow at e and openings at 0 by means whereof the said shaft can be reciprocated and the solder in the pan made to pass through said shaft, as and for the purpose set forth.

4. In combination with a stove having a pan for heating solder, the said pan having an offset chamber, D D, containing a rod-shaft, E,

having a hollow at e and openings at 0 the can-dipper H, consisting of a bottom, h, having sides h and sleeve W, with or without the inverted cover its, the counterbalanced lever F, with treadle-rod and treadle attachments, all said parts operating in the manner and for the purposes set forth.

In testimony of said invention I have hereunto set my hand.
